  • I/O Performance modelling and evaluation - giving your company the competitive edge 
    Waja, M; Blignaut, R (1995)
    I/O Subsystem performance is one of the key components that impact the business operations of today's organisations. The objective of this paper is to provide a detailed performance evaluation of various storage architectures ...
  • Ideologies of information systems and technology 
    Introna, LD (South African Computer Society (SAICSIT), 1994)
    In this paper some views and ideologies of information systems and technology will be explored. Some of these views and ideologies are clearly understood and have a high level of support. There are however more subtle ...
  • Image coding with fractal vector quantization 
    Cloete, E; Venter, LM (South African Computer Society (SAICSIT), 2000)
    In this paper, we address the time complexity problem associated with fractal image coding. In particular, we describe a new hybrid technique called Fractal Vector Quantization (FVQ), which takes advantage of the best ...
  • Image reconstruction via the Hartley transform 
    Murrell, HC; Carson, D (South African Institute of Computer Scientists and Information Technologists, 1990)
    The continuous and discrete Hartley transforms are real valued transforms that have similar properties to the continuous and discrete Fourier transforms. In addition, a fast algorithm exists for computing the discrete ...
  • The Impact of Microcomputers in Computer Science 
    Danhof, Kenneth J.; Smith, Carol L. (Computer Society of South Africa (on behalf of SAICSIT), 1979)
    This paper considers the emerging role of the microcomputer laboratory in a computer science department The components for a particular laboratory are suggested. These include the microcomputers themselves, supporting ...
  • An implementation of Linda tuple space under the Helios operating system 
    Clayton, PG; Wentworth, EP; Wells, GC; de-Heer-Menlah, FK (1991)
    We discuss the implementation of Rhoda, our Linda-like Tuple Space server which runs under the Helios operating system. The approach analyses and partitions tuple space at compile time in order to reduce the run time ...
  • An implementation of Linda tuple space under the Helios operating system 
    Clayton, Peter G.; Wentworth, EP; Wells, GC; de-Heer-Menlah, FK (th African Institute of Computer Scientists and Information Technologists, 1992)
    We discuss the implementation of Rhoda, our Linda(i)-like Tuple Space server which runs under the Helios(ii) operating system. The approach analyses and partitions tuple space at compile time in order to reduce the run ...
  • An implementation of the parallel conditional 
    Jayasekera, U; Philips, N.C.K. (South African Institute of Computer Scientists and Information Technologists, 1992)
    The parallel conditional, a natural generalisation of both Lisp's COND and Dijkstra's guarded commands, is particularly suited to parallel processing. This note describes the implementation of a preprocessor that enables ...
  • Implementing UNIX on the INMOS transputer 
    McCullagh, PJ; Smit, G de V (South African Institute of Computer Scientists and Information Technologists, 1990)
    The transputer is examined as the target for a UNIX port and specific problems encountered during implementation of a UNIX kernel in a transputer environment are discussed. Some solutions to the problems are suggested and ...
  • Implication in three-valued logics of partial information 
    Britz, K (2001)
    In formal logic, both semantic entailment and the conditional connective are used to formalize the intuitive notion of implication. The former is defined in the meta-language of the logic, and the latter in the language ...
  • Implications of emerging DRAM technologies for the RAMpage memory hierarchy 
    Machanick, P; Salverda, P (1998)
    The RAMpage memory hierarchy is an attempt at devising a comprehensive strategy to address the growing DRAM-CPU speed gap. By moving the main memory up a level to the SRAM currently used to implement the lowest-level ...
  • An Improved Implementation of Grimbleby's Algorithm 
    Schach, Stephen R. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    Details are given of an implementation of Grimbleby's algorithm for the common spanning tree problem with running times up to 50% less than for the original implementation. An explanation is given as to why implementations ...
  • Improving a control and sequencing language 
    Fair, CA; Smit, GD (1991)
    In a process control environment, batch processes, as opposed to continuous pro­cesses, are characterised by multi-product manufacturing lines producing relatively small quantities which often involves frequent product ...
  • Improving object oriented analysis by explicit change analysis 
    Yu, L; Khong, SC; Xun, Y; Yuan, M (South African Computer Society (SAICSIT), 1999)
    Changeability is one of the major concerns in software development. OO (Object-Oriented) technology itself is not enough to solve this problem, i.e. software systems cannot have enough changeability by just using any ...
  • In praise of solid state discs 
    Ridler, P.F. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    Various ways of using random access memory to emulate a magnetic disc storage system are described and the advantages and disadvantages are enumerated. An algorithm for making use of a solid state disc is given which avoids ...
  • The Independent Online: a case study of Internet publishing 
    Morris, A (1996)
    The independent online is the Internet service of Independent Newspapers, South Africa's largest newspaper group. This paper is a case study of the events of the past year, including the lessons, successes and failures ...
  • Indexing in a case-based reasoning system for waste management 
    Wortmann, KL; Petkov, D; Senior, E (South African Computer Society (SAICSIT), 1999)
    This paper presents a summary of research on indexing in Case-Based Reasoning (CBR) applied to the domain of waste management. Indexing theory and techniques are covered in order to position the results. The chosen application ...
  • Industry-academic-government cooperation to boost technological innovation and people development in South Africa 
    Van der Walt, TJ (1996)
    Cooperation between industry, academia and government is increasingly viewed to be of key importance for economies to be globally competitive. In a world where research and technology development, and the diffusion and ...
  • The influence of facilitation in a group decision support systems environment 
    Nepal, T; Petkov, D (2001)
    Organisations today face many issues that are complex and ill structured. The complexity of these issues does not lend themselves to structuring and formulation by quantitative models, or simple intuitive problem solving. ...
  • Information security awareness, a must for every organization 
    Thomson, M; Von Solms, R (2000)
    Information Technology (IT) has become part and parcel of the business world today. In fact, with the increasing sophistication of networks and the continued growth in electronic commerce, it will continue becoming an ever ...
